WebA weighted average finite difference method for solving the two-sided space-fractional convection-diffusion equation is given, which is an extension of the weighted average method for ordinary convection-diffusion equations. Stability, consistency, and convergence of the new method are analyzed. A simple and accurate stability criterion valid for this … WebJan 6, 2015 · $\begingroup$ As good an answer as one could expect appears in the following paragraph: "However, the straightforward application to robotics is not without peril as the generation of the $\Delta\theta_j$ requires proper knowledge on the system, as badly chosen $\Delta\theta_j$ can destabilize the policy so that the system becomes …

WebBy approximating both second derivatives using finite differences, we can obtain a scheme to approximate the wave equation. The main difference here is that we must consider a second set of inital conditions: . For the purposes of the illustration we have assumed that this is . The method obtained in this way is stable for . WebSo using the $\theta$-method you will end up with, ... finite-difference; advection-diffusion; conservation; or ask your own question.
